…ors, OAP authorization (#2479, #2406) Implements three missing MCP production primitives (arXiv:2603.13417) and OAP declarative pre-action authorization (arXiv:2603.20953). MCP primitives (#2479): - Add McpErrorCode enum (Transient/RateLimited/InvalidInput/AuthFailure/ ServerError/NotFound/PolicyBlocked) with is_retryable(); McpError::code() maps all variants including SsrfBlocked/CommandNotAllowed/EnvVarBlocked (PolicyBlocked), InvalidUrl/ToolListLocked (InvalidInput), Embedding (ServerError) - Add caller_id: Option<String> to ToolCall and AuditEntry for identity propagation - Add max_tool_calls_per_session: Option<u32> to [tools] config; counter in ToolOrchestrator incremented once per logical batch (not per retry) OAP authorization (#2406): - Add [tools.authorization] config section (AuthorizationConfig) with enabled flag and per-tool allow/deny rules; capabilities: Vec<String> field present, matching deferred (M4) - Authorization rules appended after policy.rules at startup in runner.rs (policy takes precedence, documented) - PolicyGateExecutor::execute()/execute_confirmed() return Err(ToolError::Blocked) when policy is enabled — no silent passthrough - Add policy_match: Option<String> to AuditEntry, populated from PolicyDecision::trace on allow and deny branches
